my circuit is for a board eraser in which if i pushed the remote, it will move in left-right direction... for example: i used the left button, then the motor must move/rotate in a direction in accordance to what i pressed.

btw here's the picture of our prototype... i also wonder if our motor could actually move the eraser :c

we made sure that we can maneuver the rollers attached in our board manually so that it would be moved also by the motor mechanically. i have already researched a lot with pic16f84a but i always end up with a not so easy-to-understand results... here is also the simulator i searched
